Drill a 12mm hole through the wall and through the first floor joist. Insert the Bow Flex tie into the Power Support tool, push the tool and tie into the drilled hole and, using the SDS hammer drill set on hammer, drive the Bow Flex tie into the second floor joist. Remove the Bow Flex Power Support tool from the hole. Note: At this stage a tensile test may be performed to proof test the fixing of the tie. Target Polyester Resin is used to bond the Bow Flex tie to the wall to complete the installation.
